// COM: Verify that hotswap-rewrite succeeds on a clang-assembled ELF where
// COM: .dynamic follows .text (the layout that previously caused
// COM: growWithTrampolines to refuse). No patches are applied here (the
// COM: kernel contains no patchable instructions), but the rewrite pipeline
// COM: must accept the ELF rather than returning an error.
// RUN: %clang -target amdgcn-amd-amdhsa -mcpu=gfx1250 -nostdlib %s -o %t.elf
// COM: Confirm .dynamic exists after .text in the input ELF.
// RUN: %llvm-readelf --section-headers %t.elf | %FileCheck --check-prefix=LAYOUT %s
